It has been a while since I did a post. I have been busy at work on some new architecture designs and intend to make a good entry contrasting Grails and Java EE5 efforts soon. However it has been a while and thought I would post up some errata thoughts I have had. It has been very interesting to see how the two efforts (Grails and EE5) deal with similar goals compared and contrasted to each other. Trying to do the same thing in two different frameworks has definitely made it easier to see how each is addressing needs. Of particular interest is comparing how grails deals with call backs from ajax widgets to server side logic compared to the Java Jmaki effort. I've got a longer post with my lessons from this that I am working on for a later date.
I selected Grails over Ruby on Rails mostly due to the access I would have to the JVM combined with the Rails approach. Also since I was wanting to contrast against a pure EE5 approach this made more sense. By pure EE5 I mean an entity bean approach combined with JSF. With the hiring of Nutter and Enebo by Sun Microsystems, Jruby (another codehaus.org effort) could becoming an interesting option too since then "Ruby" will have access to the Java API's. It has that access now I believe, however I don't believe the Ruby and Rails aspect of Ruby is fully over to the JVM yet. I do like the coding by convention vs. the XML configuration approach however. I love XML, but think we have done too much with it in places where we could just use the coding language we have available. I definately will be looking at Ruby in general and the Ruby on Rails community more.
A very interesting interview is given by Tim Bray on InfoQ. It's a great listen for anyone interested in dynamic languages, RAILs concepts, ReST vs WS and some of the issues surrounding them.
